Hi everyone Today I installed the iMac EFI Firmware update 1.7, supposed to address issues with TB ports and also Lion internet recovery. Also today I have had nothing but crashes. Kernel panics. My iMac has been completely fine until now, but now it's kernel panic every time I try to open up my latest project in Logic. Anyone else having any problems since the 1.7 EFI update, or the Thunderbolt Software Update 1.1 that came with it? I just don't know what else could be the problem. My machine is currently unusable. The other troubling thing, is that the 1.7 update page says the Boot ROM Version should be IM121.88Z.0047.B1D.1110171110 but mine is reading Boot ROM Version: IM121.0047.B1D I see it's similar, but it does not have all of the #s... does this mean the update did not finish correctly?
